Eastern House Portland House

Portland House, located at 103 Portland Street in Manchester, is a shipping warehouse built around 1870-1880 that has since been converted into offices and a club. The building likely has an iron frame and is clad in red brick laid in Flemish bond, with sandstone dressings and a slate roof. It has a trapeziform plan situated on a corner site, featuring loading access at the rear.

This eclectic-style structure stands five storeys tall, with a basement and attic, and is symmetrical with three bays. The ground floor showcases stone-banded pilasters and a bracketed cornice, along with stone bands on the upper floors. Between the second and third floors, there are moulded terracotta panels, and the plain frieze is interrupted at the centre. The steeply-pitched roof has a hipped gable at the centre, topped with a finial.

The ground floor includes a square-headed doorway with a moulded surround and a plain frieze that has the attached lettering "PORTLAND HOUSE." This doorway is flanked by pairs of segmental-headed windows above basement openings. The first, second, and third floors feature three-light windows with stone mullions. The centre windows on the first and second floors are set in a segmental oriel, with a carved panel between the two floors. The upper floor has segmental-headed lights, a dentilled cornice, and a brick parapet, while the first-floor windows in the outer bays have pilaster mullions and segmental pediments above the centre light. The third-floor windows are segmental-headed with keystones, and there are pairs of one-light windows on the fourth floor, along with flat-roofed dormers over the outer bays and gable chimneys.

The left return of the building, which includes numbers 40 to 46 Princess Street, has seven bays that match the style of the main façade. It is symmetrical with hipped gables on the second and sixth bays and a square-headed loading bay entrance in the centre. The rear and interior of the building have not been inspected. Portland House forms part of a group with No. 101 on the opposite corner of Princess Street, as well as Nos. 105, 107, 109, 111, and 113 to 119, together creating a complete block of former shipping warehouses.
